To all whom it may 001mm:

Be it known thntl, ()ununns S. Union, a. citizen of the United States of America, and a resident of the city of Summit, State oi New Jersey, have invented certain new and uselul lm u'oveineuts in Timers, the principlea of which are set forth in the following specification and accompanying drawings, which disclose the form the various forms in which those of the invention which 1 now consider to be the best of principles may be enibodied.

This invention relates to improvcuienls in devices known in the art asiil11mzi.flnd used with the spark-producing apparatus of gas engines, particularly of the type used as automobile motors.

The object of the invention is to produce a, i'eiinb1}- acting and durable timer, one in which the electrical contact is positively made and quickly broken, and without any thrusting-strain tending to injuge the structure.

The invention consists in the means, hereinafter disclosed and claimed, for accomplishing this obje t.

Ofthc drawings. Figure 1 is a side elrstiun of the complete device, except that a cover is? the right hand side and proiocting end of Fire shaft is removed and not shown; Fig. 2 is a front elvation looking into the interior oi the device, the cover heing removed, and the lower right hand part of the figure being in section along the line 1-l oi Fig. 1, to show inierior parts; Figv 3 isu section aiong the line 2--2 of Fig. 2; and Fig.4 is an oh, vation oi the axial ports shown in section in Fig. 3.

The drawings show four contactanahors, one [or each cylinder of a four-cylinder engine. The device will have as many contact-makers as there are engine cylinders.

It is well known that timers have given grout troub e, owing not only to the unsatisfactory and unreliable making of Contact, but to the ihrusting'stmins which weaken and eventually break down the structure. Efforts to improve the contoctonaking have in caressed the thrusting strains, and as the cont-action kor moves with considerable velocity, the effects of these strains have been serious. lly this invention :1 salisfm tory Contact. is made, yet without any thrust. which mix strain the structure. A snap-break action in these do vices has been an object oi enden vor, but ei'iorls to em ploy it; have resulted in it coinpliculion of parts. By this invention the Contact. is broken with u snap-action, although the contact-maker consists of bu I. one incniher.

in Fig. 2, the Contact maker A, rotated nnti-cinciiwise (Hoe arrow), as by the motor-shah, is shown in engagement with the movable contact B at the instant when it first makes contact therewith. lt thenv pushes ii in the right. against a spring S, thus insuring an ndequaie electrical. contact. llut. A, although moving at; high speed, causes no tlmustingstrain which is not yieidingiy met by spring S. This in due to the fact that contact; B

is made so movable. Hill is so located, with respect 0 the direction of motion of A, that substantially all the nicclmnicul energy oi A is expended in moving B, and in moving it in substantially the some direction as the direction of motion of A; and substantially none of the energy of A is expended in any thrust which would cause a strain on the structure. The rotating motion of A, however, causes a useful wining action between A and ii which improves the eicctricni connection, this action being due to the fact that. A while in roiniion is in engagement with ii whiie ll is boing forced to move recliiinearly. If desired, the contact I! may be so inuwbly mounted as to suhetaniinlly ciinu'nnie the wiping contact action. lml the nwuniing shown is preferred because it permits such action. A and B are made of tool steel. and their rubbing or wiping contact 7 will not cause myid wearing, The coniact B is free to rotate in its bearings when not engaged byA. and the jarring oi the structure when in use will cause I? to rotate and present to A .Lli ports of the periphery of itsop erutive end so tlutt it will not wear in one place alone.

Thc part of A which cugngcs with l! is iint and at such an nnglc as to abut Rqtitll'tl) :igaiinst H, ihus providing a maximum coninct-ui'cu. The dotted lincs in Fig. 2 show A after its wiping action on I}, wlicn it is about to movc out oi cngngcmcnt with ll. As soon as it so IDOVl'S, 1% is smippcd l)flf'l by spring S, and as the cdge of A is cut sharply upward to the loft, thc contact is coiuplctcly brokcn hy u unzip action, notwithstnuding that the rcium nmvcuicnt of ll undcr prcssucc of spring h is in a dircction oppositc to that of the mom-incur; of A 2% thc tinu: oi (:(HlLttl-ll'ittklllg impact.

In addition to thc chm-actor oi its direction of nmiinn, B inso mountcd thut it rcccivcs directly the full impact of A in its dircctiou of movcmont, and 1% is so mounted that such thrust docs not act obliqucly or angulnrly on the boar ings of ii on as to impart. it strain thereto.

Thc arrangement shown, consisting in making 1% movable substantially tangent to thc. are of rotation of A, constitutes an excellent enihoilinient of lhe iuvenlion There in not simply relative motion of or ll addition to tho rotaiion of A ll in m loutlml with reaped to A, that the powerful lhruHt lllll lo the high npeeil of A l whn-h thrust eontinuen to exist in n llegrweven when the parts have Puvh relative Freedom of uiolion, mi l in :in ohjr-et of the invention in order to Hvlllrl reliul-h' ainl vermin vontaeI-nralaingr inn new-rlhehw inipmi no strain to the h aring of ll. ll. hut in permitting it n; mow H'Hlt'l lln :lmnu of "i no nhmrn. not unit are the heuri nyr; of it w ll Ir n all r-lfeelive strninn, Inn All llnmpporln of ll iln-huling: that whieh is nnhslunliully in linlwill! tln i'reetion of movement oi A ul il tim ol impact ill'l Err-mi the bearinpsot' ll uriremoved in iln reluiiwlommon.
